The chemical element with the symbol Pb is Lead. The symbol Pb comes from the Latin word plumbum, which means lead. Lead is a heavy metal that is denser than most common materials. It is soft, malleable, and has a relatively low melting point.
Lead has been used by humans for thousands of years, dating back to ancient civilizations. It was commonly used in pipes, plumbing, and even in paints. However, due to its toxicity, the use of lead has been significantly reduced in modern times, especially in products that come into contact with humans, such as paint and gasoline.
In the periodic table, lead is found in group 14 (carbon group) and period 6. It has an atomic number of 82, which means it has 82 protons in its nucleus. Lead is a post-transition metal and is known for its high density and resistance to corrosion.
